I just finished my cam mod, and everyone was right..its amazing. I also did the BK mod in a few minutes..WOW throttle response.. Thanks to everyone that gave my input, and to those who posted before (which I found in my searches) My Question-- When I completed my mod, the motor seems to have some new engine noise. Anyone else experience this? My riding buddy, he rides a KTM and has extensive 4-stroke history, says it seems normal to him and that my bike was always too quite with engine noise. Should I worry about anything?
